BLIOVLCLR()
------------------------------------------------------------------------------
Purpose:
Clear unused CA-Clipper Summer '87 overlays from memory.
Syntax:
BLIOVLCLR()
Parameters:
None.
Returns:
None.
Description:
This function is only effective with the BLINKER OVERLAY DYNAMIC method
of overlay allocation (CA-Clipper Summer '87 only). It performs no
function with the BLINKER OVERLAY FIXED method of overlay allocation.
This function is used to force the Blinker overlay manager to clear out or
discard all inactive overlay procedures from the overlay pool and return the
memory used by them to CA-Clipper.
This may be used in the main module of an application to ensure that
CA-Clipper has the maximum amount of dynamic memory available before
executing another overlay.
Once all inactive overlays are flushed, the overlay pool operating size is
reset to a maximum of the default size or the total size of the active
overlays. The default size when the application starts is the most recent of
the link time BLINKER OVERLAY OPSIZE <size> command or the /OOnn parameter
in the BLINKER environment variable.
Example:
// Clear all inactive overlays
//
BLIOVLCLR()
